Maytag Dishwasher Smells Bad — What’s Happening
A bad smell in a Maytag dishwasher is not a fault code. It is an odor complaint that points to organic buildup, trapped debris, or contamination in the drain path. Maytag treats this as a maintenance issue rather than an electronic failure.
The manufacturer directs you to inspect the filter, spray arms, interior surfaces, door seals, and drain or disposer connection. Standing water, food particles, soap scum, grease, mold, and mineral deposits can all hold odors and intensify bacterial smell over time.
Most Likely Causes
- Food debris in the filter or sump area Maytag identifies the drain filter as the first place to check when odor is present.
- Blocked spray arms leaving residue behind Clogged jets prevent proper water circulation and allow food and grease to accumulate.
- Drain obstruction or food caught in the drain path Trapped debris in the dishwasher drain or garbage disposer connection can cause persistent smell.
- Grime or mold on door seals and interior surfaces The door gasket and tub walls hold moisture and organic residue that produce odor.
- Standing water or poor draining Water that does not drain fully encourages bacterial growth and intensifies smell.
- Soap scum, grease, and mineral buildup in hard water Residue from detergent and minerals creates a film that traps odor-causing bacteria.
How to Diagnose and Fix
- Confirm whether the smell is present with the tub empty, after a wash, or only when opening the door to help distinguish residual odor from a drain-back issue.
- Remove the lower rack, take out the drain filter, and rinse it under hot water to clear trapped food particles.
- Remove or access the spray arms, check for blocked jets, and clear any debris so wash water can circulate normally.
- Inspect the dishwasher drain and garbage disposer connection for food or obstructions, and run the disposer to clear it if connected.
- Wipe down the tub, racks, and door seals with a damp cloth and mild detergent to remove grime and organic residue.
- Run an empty hot cycle with affresh or white vinegar as Maytag recommends for odor removal.
- Recheck after cleaning, and if odor persists, re-open the filter, sump, and drain path to inspect for hidden debris or recurring drain-back.

When to Call a Pro
Call a technician if the odor persists after cleaning the filter, spray arms, drain path, and seals, or if you find standing water that will not drain even after clearing visible obstructions. A pro can diagnose hidden drain-path issues, check for drain-pump failure, or replace damaged components like the door gasket or drain hose that may be contributing to backflow or contamination.
